Severino walked one and did not allow a hit while striking out three across 1.1 scoreless innings Thursday against Seattle.
Severino was recalled from Triple-A Charlotte earlier in the week with Lucas Giolito (abdomen) and AJ Pollock (hamstring) both hitting the injured list. He pitched well in his major-league debut, though Severino struggled with his control as he both issued a walk and hit a batter. While he has good strikeout stuff, the 27-year-old has posted elevated walk rates throughout the minor leagues. He is likely to remain in a low-leverage role out of the bullpen.
